篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Sphinx 之 CoreseekSphinx-for-chinaeseSphinx+Scws 评测相关的知识，希望对你有一定的参考价值。
Sphinx是一个基于SQL的全文检索引擎；普遍使用于很多网站；但由于中英文的差异，其本身，对中文的支持并不好。
主要体现在对一段话断词；英文只需按照空格对其分词即可；但对于博大精深的中文来说，却是件困难的事情。
分词在两个地方会用到；
1、索引时，根据分词索引原始数据
2、搜索时，对用户输入分词，到索引中查询
本文提供了三种目前最常用的方案Coreseek、Sphinx-for-chinaese、Sphinx+Scws，并对其简单对比；在合适的场景，选择合适的方案，得出最优的解。
评测：
一、Coreseek 为国人基于Sphinx开发的方案，目前最稳定版，是基于经典的Sphinx0.9.9版
优点：有成熟的文档、以及社区；其分词mmseg为目前国内最为好用分词，索引和搜索分词都可以用到；
缺点：深度开发、版本更新较慢；索引较慢
策略：一个词库管理后台，维护词库；定期生成字典；此套件会自动分词索引；
适用场景：普通青年、搭建差不多的搜索，适用于普遍网站
二、Sphinx-for-chinaese 为国人2基于经典的Sphinx0.9.9版开发的扩展版
优点：部署简单，易操作，内嵌分词和词库，索引和搜索分词都可以用到；
缺点:版本更新较慢；分词较弱；索引相对较慢
策略：同一
适用场景：普通青年、快速搭建搜索的小站
三、Sphinx+Scws 为两套独立系统，单独部署，所谓高内聚低耦合，强烈推荐
优点：两套系统，相对独立，各自单独Server；分词可以做其他用途；版本更新较快；
缺点：部署稍复杂，使用稍复杂；索引分词只能用一元分词，数据量较大
策略：词库管理外；使用时，先调用分词服务，后调用搜索
适用场景：文艺青年、搭建像样点的搜索；好吧文艺青年
由于本人强烈推荐方案三，对方案三有详细描述，其他方案仅提供简单部署方式。
三种方案具体实现如下:
一、coreseek
=======================================================================================================
官网 http://www.coreseek.cn
基础库 http://ftp.gnu.org/gnu/automake/
1、安装
1.0 基础库
#设置路径和中文环境：
export PATH=/usr/local/bin:$PATH
export LC_ALL=zh_CN.UTF-8
export LANG=zh_CN.UTF-8
#依赖包安装顺序
m4、autoconf、automake、libtool
./configure –prefix=/usr/local
make && make install
1.1 安装mmseg
./bootstrap
./configure –prefix=/opt/server/mmseg
make
make install
1.2 安装csft
sh buildconf.sh
./configure –prefix=/opt/server/coreseek –without-unixodbc –with-mmseg=/opt/server/mmseg –with-mmseg-includes=/opt/server/mmseg/include/mmseg/ –with-mmseg-libs=/opt/server/mmseg/lib/ –with-mysql=/opt/server/mysql
make
mkae install
1.3 配置
mv csft_mysql.conf /opt/server/coreseek/etc
配置 /opt/server/coreseek/etc/csft_mysql.conf 参数 ；注意编码问题；
#源定义
source mysql
{
type = mysql
sql_host = 127.0.0.1
sql_user = root
sql_pass = 123456
sql_db = test
sql_port = 3306
sql_query_pre = SET NAMES utf8
sql_query = SELECT id, group_id, UNIX_TIMESTAMP(date_added) AS date_added, title, content FROM documents
#sql_query第一列id需为整数
#title、content作为字符串/文本字段，被全文索引
sql_attr_uint = group_id #从SQL读取到的值必须为整数
sql_attr_timestamp = date_added #从SQL读取到的值必须为整数，作为时间属性
sql_query_info_pre = SET NAMES utf8 #命令行查询时，设置正确的字符集
sql_query_info = SELECT * FROM documents WHERE id=$id #命令行查询时，从数据库读取原始数据信息
}
#index定义
index mysql
{
source = mysql #对应的source名称
path = /opt/server/coreseek/var/data/mysql #请修改为实际使用的绝对路径，例如：/usr/local/coreseek/var/...
docinfo = extern
mlock = 0
morphology = none
min_word_len = 1
html_strip = 0
#中文分词配置，详情请查看：http://www.coreseek.cn/products-install/coreseek_mmseg/
charset_dictpath = /opt/server/mmseg/etc/ #BSD、Linux环境下设置，/符号结尾
#charset_dictpath = etc/ #Windows环境下设置，/符号结尾，最好给出绝对路径，例如：C:/usr/local/coreseek/etc/...
charset_type = zh_cn.utf-8
}
#全局index定义
indexer
{
mem_limit = 128M
}
#searchd服务定义
searchd
{
listen = 9312
read_timeout = 5
max_children = 30
max_matches = 1000
seamless_rotate = 0
preopen_indexes = 0
unlink_old = 1

log = /opt/server/coreseek/var/log/searchd_mysql.log
query_log = /opt/server/coreseek/var/log/query_mysql.log
}
1.4测试
/opt/server/coreseek/bin/indexer -c /opt/server/coreseek/etc/csft.conf –all
/opt/server/coreseek/bin/search -c /opt/server/coreseek/etc/csft.conf 网络搜索
1.5词库管理
词库文件
/opt/server/mmseg/bin/mmseg -u /opt/server/mmseg/etc/unigram.txt
unigram.txt.uni 更名为 uni.lib 放入对应字典目录
二、sphinx-for-chinese

3、启动服务
/opt/server/sphinx/bin/searchd
4、php分词 scws
官网 http://www.ftphp.com/scws/
4.1 安装
./configure –prefix=/opt/server/scws
make
make install
4.2 词库
scws-dict-chs-utf8.tar.bz2 解压放入 /opt/server/scws/etc
词库 dict.utf-8.xdb
规则 rules.utf-8.ini
4.3 php 扩展
源码在 phpext下
/opt/server/php/bin/phpize
./configure –with-scws=/opt/server/scws –with-php-config=/opt/server/php/bin/php-config
make
make install
vi php.ini
[scws]
extension = scws.so
scws.default.charset = utf-8
scws.default.fpath = /opt/server/scws/etc
查看
/opt/server/php/bin/php -m |grep scws
4.4 分词测试
官方测试地址：http://www.ftphp.com/scws/docs.php
详见测试文件 test_all.php
<?php
echo ‘<p>‘.microtime(true).‘</p>‘;
//搜索词
$key = trim($_GET[‘k‘]);
//========================================分词
$so = scws_new();
$so->set_charset(‘utf-8‘);
//默认词库
$so->add_dict(ini_get(‘scws.default.fpath‘) . ‘/dict.utf-8.xdb‘);
//自定义词库

}
$so->close();

echo ‘<p>分词：‘.$words.‘</p>‘;
//var_dump($words);
//exit;
//========================================搜索
require_once ‘sphinxapi.php‘;
$sc = new SphinxClient();
$sc->SetServer(‘127.0.0.1‘,9312);
$sc->SetMatchMode(SPH_MATCH_ALL);
$sc->SetArrayResult(TRUE);
$res = $sc->Query($words);
var_dump($res);
echo ‘<p>‘.microtime(true).‘</p>‘;
exit;
?>
其他高阶操作
=======================================================================================================
5 索引
//索引某个索引
/opt/server/sphinx/bin/indexer test1
//searchd 索引某个索引
/opt/server/sphinx/bin/indexer test1 –rotate
//指定索引搜索
/opt/server/sphinx/bin/indexer -i test1 ‘逗她男’
5.1 增量索引方案
//创建表记录偏移
CREATE TABLE search_counter
(
counterid INTEGER PRIMARY KEY NOT NULL,
max_doc_id INTEGER NOT NULL
);
//增量索引
/opt/server/sphinx/bin/indexer test1stemmed –rotate
//合并索引
/opt/server/sphinx/bin/indexer –merge test1 test1stemmed –rotate
索引策略
1、搜索时，同时从主索引和增量索引取数据
2、每5分钟，运行一次增量索引；满足新数据搜索需求
3、每晚，运行一次主索引，同时会更新索引标示；再运行增量索引，实质为清空增量索引，避免与主索引重复
4、好处：避免开合并索引，合并索引效率较差
5、如数据量特别大，可考虑合并索引的方案
索引策略shell
//add.sh
#!/bin/sh
/opt/server/sphinx/bin/indexer test1stemmed –rotate >> /opt/server/sphinx/var/log/add.sh.log
//all.sh
#!/bin/sh
/opt/server/sphinx/bin/indexer test1 –rotate >> /opt/server/sphinx/var/log/all.sh.log
/opt/server/sphinx/bin/indexer test1stemmed –rotate >> /opt/server/sphinx/var/log/add.sh.log

5.2 实时索引
策略：
在插入Myslq数据的同时，将需要索引的数据，同时往sphinx 虚拟Mysql数据库写入一份，实时索引
应用场景：
对实施搜索要求非常要的应用，一般不推荐此方式，尚且不稳定
方案：
编写相关PHP类，在Myslq插入数据的类中，同时插入索引数据，对前端使用者无需关心逻辑
详情配置

5.3 多个表独立索引方案
场景：如有用户搜索、商品搜索等多个索引需求
策略：
配置一个多索引方案，每个表单独建立索引
前端根据不同类型选择不同的查询索引；全部，即选择所有索引
